In this hour and a half long podcast they talk about a lot of stuff, including:

Canon’s surprise when HD video took off

Nikon foot dragging on 1080

How to get started in video

Difficulties in doing shoots

Should a Nikon shooter switch back to Canon?

Latitude of digital compared to film

Overheating

Do you need stabilized lenses?

There's a lot of other stuff covered; this list just scratches the surface. While a lot of the focus is on still photographers moving to video, anyone getting started in DLSR video will get something out of this.
